Iowa Supreme Court holds that the constitutionality of a search should be evaluated by the law of the sovereign that initiated and conducted the search—not by the law of the sovereign that had nothing to do with the search. Hence, if an individual is on federal probation, and federal officers conduct a search, then the interpretation of the federal constitution determines whether the search is legal, not the interpretation of the Iowa constitution, even if the State of Iowa ultimately is the entity that prosecutes the individual under state law and the search may not have been constitutional under the State of Iowa’s constitution.
